## What ocean-science does, in the publisher's words

Physical oceanography for Open Science Pillars: the ECCO v4r4 state estimate, SWOT KaRIn SSH, meridional transport, budget closure, water masses, sea level, and the PO.DAAC knowledge arc.

This capability builds on core's foundation skills and its start / discover-data / report workflows, and on the PO.DAAC provider knowledge in nasa-daac-knowledge. It declares both as dependencies, so one install brings them with it.

A Hydrosphere capability, discipline Ocean Physics (.osp/repository.yaml; ADR A in the marketplace repository). Its knowledge (KNOW) is the PO.DAAC bundle, signed by that provider's stewards and consulted in place, plus the local conventions and connectors here; its behavior (ACT) is the skills; its verification (PROVE) is the golden notebooks here and the attested computations in the provider bundle, whose receipts any runtime's result can be checked against; its connectors (REACH) are in.mcp.json. The Claude package files are the runtime projection of.osp/package.yaml.

## Skills

- briefing-generator: Generate a receipted regional sea level briefing: fills the template strictly from a PASS attested-run receipt and signed concept text, with per-DOI citations. Keywords: briefing, sea level, coastal, receipt, attested, report.
- budget-closure: Closed property budgets on native model grids: tendency, advection, diffusion, forcing terms; machine-precision residual expectations.
- cite-ecco: Emit the exact ECCO Consortium citation block with per-collection DOIs (PO.DAAC template) for the ECCO collections an analysis touched. Keywords: cite, citation, DOI, ECCO, acknowledge, references.
- compare-obs: Compare model or state-estimate output against observations: RAPID, Argo climatologies, altimetry; consistent masking and uncertainty framing.
- ecco: ECCO v4r4 ocean state estimate: LLC90 native grid, PO.DAAC collections through the fields concepts, budget formulation, dynamical consistency. Knowledge first.
- load-ecco: Load ECCO v4r4 data from PO.DAAC with grid auto-merge and Dask; volume confirmation gate; restates applicable gotchas.
- load-swot: Load SWOT KaRIn SSH regionally: parse region, cycles, tier; volume gate; flag decoding; swath-aware summary.
- meridional-transport: Meridional heat, volume, freshwater transport: section masks, overturning and gyre decomposition, RAPID comparison at 26.5N.
- mixed-layer-analysis: Mixed layer depth analysis workflow: criterion choice, seasonal climatology, trend with uncertainty.
- mixed-layer: Mixed layer depth: density and temperature criteria, seasonal cycle, sensitivity to threshold choice.
- ocean-budget: Ocean property budgets on the native ECCO grid only; refuses regridded budgets; budget-auditor auto-run on residuals.
- ocean-grids: Ocean model grids: Arakawa C-grid, LLC tiles, cell geometry, xgcm, scalar vs vector regridding rules.
